In a simple cubic lattice d100: d110: d111 is
where d is interpianer spacing.
Detailed Solution for Test: Structural of Metals & Alloys - 2 - Question 10

Correct Answer :- D

Explanation : d100 = a/(12 + 02 + 02)1/2

= a

d110 = a/(12 + 12+ 02)1/2

= a/(2)1/2

d111 = a/(12 + 12 + 12)1/2

= a/(3)1/2

d100 : d110 : d111 = a : a/(2)1/2 : a/(3)1/2

= 61/2 : 31/2 : 21/2
